12V 46Ah Dakota Lithium U1 LiFePO4 Battery

(16 customer reviews)



Engineered in a 35Ah U1 SLA case, but with 46Ah of Lithium Iron Phosphate (LiFePO4) technology, this battery has three times the power, half the weight, and lasts 5 times longer than a U1 sealed lead acid battery – providing exceptional performance & lifetime value.

Storage Capacity

46 ampere hours (Ah). Dakota Lithium batteries provide consistent power for all 46 amp hours. DL LiFePO4 batteries have a flat voltage curve, which means they have a steady power output as the battery discharges. The power output will not dramatically drop like similar sized SLA batteries. You get all the juice down to the last drop.


12.8V (Dakota Lithium 12V batteries can be used in series for up to 48V systems)


7.6”L x 5.1” W x 6.8” H (194mm x 132mm x 173 mm). U1 size (Group 21)

Drop in Replacement Size U1 35Ah SLA

U1 equivalent for physical dimensions & terminal compatibility.


552 Watt-hours (Wh)


F12 terminals (posts that screw in) with M6 size bolts. Max torque 15 ft. lbs.


10.5 lbs (4.75 Kg). 65% lighter than a SLA or lead battery.

Lifecycles (battery lifespan)

Up to 80% capacity for 6,000 cycles in recommended conditions. The typical SLA has 500 cycles. Dakota Lithium batteries last so long that the price per use is a fraction of traditional batteries.

Operating temperature

Ideal for rugged & harsh environments. Much better than SLA or other lithium batteries. -20'F min, +150'F max optimal operating temps (battery performs well down to -20'F). Avoid charging below 32'F. Discharge cut off at - 20'F / -20'C. Charge cut off at 23'F / - 5'C. BMS high temp cut off at 167'F / 75'C.


50 A max continuous discharge. The flat discharge voltage curve provides a 3X bigger capacity then a U1 SLA 35Ah battery.


Recommend for longest life 10A or less (.2C), Max continuous 23A (.5C). 14.4 V recommended, 15 V max, BMS protection from over charging will cut off at 15V. Included is a free 12V 10 Amp (A) LiFePO4 compatible charger that charges at the recommended 14.4 Volts..

Includes active BMS protection

Contains a high discharge capable circuit that handles cell balancing, low voltage cutoff (10V) preventing over discharge, high voltage cutoff (15V) preventing over charging, short circuit protection and temperature protection for increased performance and longer life.

Cold temperature charging protection

No low temperature protection


All DL batteries are UN 38 certified. Dakota Lithium's cells are UL1642 certified and have been tested per IEC62133 standards. Meets all US & International regulations for air, ground, train, & marine transport.

Trolling Motor Compatibility

Perfect for trolling motors with 30 lbs of thrust or less. For larger 12v motors the DL+ 12V 60Ah battery is recommended. For 24V & 36V trolling motors the single 24V 60 Ah or 36V 60 Ah batteries are recommended.

Charger Included

Free 12V 10A LiFePO4 charger included

Suitable for:

  • Deep Cycle Applications
  • Marine Applications
  • Drop in Lithium replacement for U1 35Ah SLA batteries
  • Garmin Livescope
  • Lowrance Fish Finders
  • Trolling Motors <30lbs of thrust #FishLonger
  • Mobility Scooters
  • Electric Wheel Chairs
  • Link in series for 24 Volts

Experience the Dakota Lithium Difference

The Dakota Lithium 12V 46Ah battery is built with Dakota Lithium's legendary LiFePO4 cells. 6,000+ recharge cycles (roughly 10 year lifespan at daily use) vs. 500 for other lithium batteries or lead acid. Optimal performance down to minus 20 degrees Fahrenheit (for winter warriors). Plus three times the power of lead-acid batteries at half the weight.

Great Products and Great Service!

Already have two 12V/100ah running my 24V troll motor flawlessly while saving on weight and decided to add some electronics up front with their own dedicated battery source.

This New 12V/46ah DL looks to be the perfect match/setup for the Newly added and older electronics while weighing in at just over 10#’s!

Thats Money well spent right there!

Thanks DL and appreciate the Great Products and Service!

Best batteries around


I replaced a 23ah battery with a 46ah battery. I will be heading to Sardis lake in Mississippi on the 19th of March. I have a Garmin 10” depth finder and a Livescope setup on my boat. The 23ah was not enough power to run the depth finder and the Livescope at the same time. I sent the 23 ah Dakota Lithium battery back and replaced it with the new 46ah Dakota Lithium battery. I am very pleased with the customer service and great advice about the amperage needed to power my units. I will recommend Dakota Lithium to anyone.
